Capital near the Great Divide (6)
I believe the answer is:
helena
'capital near the great divide' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for helena that I've seen before include "- - Bonham-Carter, actress" , "-- Bonham Carter, actress" , "Island saint in the South Atlantic" , "St ---, where Napoleon died" , "Saint who was a Roman empress" .)
